Strawberry plant named ‘SB_13_177-015’

ABSTRACT

This invention relates to a new and distinct variety of strawberry plant named ‘SB_13_177-015’. This new strawberry plant named ‘SB_13_177-015’ is primarily adapted to the growing conditions of West Central Florida, and is primarily characterized by its achenes typically set even with the surface of the fruit, moderately vigorous plant habit, high marketable yield, early time of first flower and fruit, and large berry size.

Latin name of the genus and species of the plant claimed: Fragaria ananassa.

Variety Denomination: ‘SB_13_177-015’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct strawberry variety named ‘SB_13_177-015’. This new variety is a result of a controlled cross made in 2013 in an ongoing breeding program between strawberry variety designated ‘FL 05-107’ (U.S. Plant Pat. No. 23,042) as the seed (female) parent, and strawberry variety designated ‘PS-3.108’ (U.S. Plant Pat. No. 23,291) as the pollen (male) parent. The variety is botanically known as Fragaria ananassa.

The seedling resulting from the aforementioned cross was selected from a controlled breeding plot in Hillsborough County, Fla. in the fall/winter of 2014-2015. After its selection, the new variety was asexually propagated by stolons in both Siskiyou County, Calif. and San Joaquin County, Calif. The new variety was extensively tested over the next several years in fruiting fields in Hillsborough County, Fla. This propagation has demonstrated that the combination of traits disclosed herein as characterizing the new variety are fixed and remain true-to-type through successive generations of asexual reproduction.

BRIEF SUMMARY OF THE INVENTION

‘SB_13_177-015’ is primarily adapted to the climate and growing conditions of West Central Florida. The subtropical climate of West Central Florida provides the day length and moderate temperatures needed to produce an early yielding, vigorous plant and maintain fruit quality during the fall and winter production months.

The following traits have been repeatedly observed and are determined to be unique characteristics of ‘SB_13_177-015’, which in combination distinguish this strawberry plant as a new and distinct variety:

-   -   1. Achenes typically set even with the surface of the fruit;     -   2. Moderately vigorous plant habit;     -   3. High marketable yield;     -   4. Early time of first flower and fruit; and     -   5. Large berry size.

‘Florida Brilliance’ (U.S. Plant Pat. No. 30,564) is currently the dominant strawberry variety in Hillsborough County, Fla. The fruits of ‘SB_13_177-015’ are similar in color and shape to ‘Florida Brilliance’, but the plant habit of ‘SB_13_177-015’ is smaller and less open. The achenes of ‘Florida Brilliance’ are more sunken than those of ‘SB_13_177-015’. In side-by-side comparisons from the 2021-2022 season (Nov. 23, 2021 to Feb. 25, 2022) ‘SB_13_177-015’ compares with ‘Florida Brilliance’ (U.S. Plant Pat. No. 30,564) in the following combination of characteristics as described in Table 1.

TABLE 1 ‘Florida Brilliance’ ‘SB_13_177- (U.S. Plant Pat. Characteristic 015’ No. 30,564) November marketable yield (gm/plt) 44 18 Season marketable yield (grm/plt) 655 818 November average berry size (gm) 24.0 27.4 Season average berry size (gm) 29.2 27.7 Average runners/plant 3.8 5.5

For identification, a series of molecular markers have been determined for this new variety.

‘SB_13_177-015’ compares with its parents, ‘FL 05-107’ and ‘PS-3.108’ by the following combination of characteristics as described in Tables 2 and 3.

TABLE 2 ‘FL 05-107’ (U.S. Plant Pat. Characteristic ‘SB_13_177-015’ No. 23,042) Fruit: size Large Medium Fruit: marketable yield High High Fruit: flavor score (1-5) Ranges from 2.5 to 3 Ranges from 3 to 3.5 Fruit: seed position Even with surface Slightly below surface

DETAILED BOTANICAL DESCRIPTION

The new variety ‘SB_13_177-015’ has not been observed under all possible environmental conditions. The characteristics of the new variety ‘SB_13_177-015’ may vary in detail, depending upon variations in environmental factors, including weather (temperature, humidity and light intensity), day length, soil type and location. In addition, the characteristics of any parental variety or comparison variety included in Table 1 of the present invention may vary in detail, depending upon variations in environmental factors, including weather (temperature, humidity and light intensity), day length, soil type and location.

The aforementioned photographs, together with the following description of the new variety ‘SB_13_177-015’, unless otherwise noted, are based on observations taken during the 2021-2022 growing season in Hillsborough County, Fla. These measurements and ratings were taken from plants of ‘SB_13_177-015’ dug from a high-elevation nursery located in Siskiyou County, Calif. during mid-September 2021 and planted approximately four to five days later in Hillsborough County, Fla. The approximate age of the observed plants is four months. Yield observations including average weight and marketable yield, along with fruit quality characteristics including soluble solids, were measured during the 2021-2022 growing season. Flower measurements and characteristics are from secondary flowers unless otherwise noted. Fruit characteristics and measurements are from secondary fruit, unless otherwise noted.

Where noted, color terminology follows The Royal Horticultural Society Colour Chart, London (2015).
